English CPU Host Frequency(Mhz) 100Mhz ~ 600Mhz Set CPU Host Clock from 100 MHz to 600 MHz. The actual range depends on the CPU you install. If you use a 533 MHz FSB processor, please set CPU Host Frequency to 133 MHz. If you use an 800 MHz FSB processor, please set CPU Host Frequency to 200 MHz. If you use a 1066 MHz FSB processor, please set CPU Host Frequency to 266 MHz. PCI Express Frequency(Mhz) Auto Set PCI Express frequency automatically. (Default value) 90Mhz ~ 150Mhz Set PCI Express frequency from 90 MHz to 150 MHz. C.I.A.2 C.I.A.2 (CPU Intelligent Accelerator 2) is designed to detect CPU loading during software program executing, and automatically adjust CPU computing power to maximize system performance. If you wish to adjust the item manually, set "System Voltage Control" to "Auto" to optimize the system voltage settings. Disabled Disable this function. (Default value) Cruise Set C.I.A.2 to Cruise. Automatically increase CPU frequency(5%,7%) by CPU loading. Sports Set C.I.A.2 to Sports. Automatically increase CPU frequency(7%,9%) by CPU loading. Racing Set C.I.A.2 to Racing. Automatically increase CPU frequency(9%,11%) by CPU loading. Turbo Set C.I.A.2 to Turbo. Automatically increase CPU frequency(15,17%) by CPU loading. Full Thrust Set C.I.A.2 to Full Thrust. Automatically increase CPU frequency(17%, 19%) by CPU loading. Warning: Stability is highly dependent on system components. System Memory Multiplier The adjustable range will vary based on the CPU FSB. Default value: Auto (set memory frequency by DRAM SPD data). Wrong frequency settings may cause system unable to boot. Clear CMOS to overcome wrong frequency issue. If you wish to adjust the item manually, set "System Voltage Control" to "Auto" to optimize the system voltage settings. Memory Frequency (Mhz) The first memory frequency value is the normal frequency of the memory being used; the second is the memory frequency automatically adjusted according to the CPU Host Frequency(Mhz) and System Memory Multiplier settings. High Speed DRAM DLL Settings Provides two different DRAM Timing configurations. If your system becomes unstable after you overclock the DDR2 memory, select Option 1 or Option 2 to help make your system more stable. Option 1 DRAM Timing Configuration 1. (Default value) Option 2 DRAM Timing Configuration 2. GA-965G-DS4 Motherboard - 46 -
